integral from 0 to pi/2 of e^x+cos(x)

\int_{0}^{\frac{π}{2}} e^{x} + cos (x) d x

e^{\frac{π}{2}}

Solution steps

\int_{0}^{\frac{π}{2}} e^{x} + cos (x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{\frac{π}{2}} e^{x} d x + \int_{0}^{\frac{π}{2}} cos (x) d x

\int_{0}^{\frac{π}{2}} e^{x} d x = e^{\frac{π}{2}} - 1

\int_{0}^{\frac{π}{2}} cos (x) d x = 1

= e^{\frac{π}{2}} - 1 + 1

Simplify

= e^{\frac{π}{2}}

\int_{0}^{z} e^{t^{2}} d t

\int_{0}^{2} 2 π (x - 3) x^{2} d x

\int_{- 1}^{1} (x^{3} - 3 x^{2} - x + 3) d x

\int_{0}^{1} \frac{2}{x ^{2}} d x

\int_{2}^{6} - x^{2} + 8 d x
